2 Introduction

2.1 Basic Features

X3-Hybrid G4 series is a high-quality inverter that can convert solar
energy into alternating current and store energy into batteries.
The inverter can be used to optimize self-consumption, stored in
batteries for future use or fed into the public grid. The way it works
depends on user preferences. It can provide emergency power during
power outages.

2.2 Electrical Block Diagram of The System

X3-Hybrid G4 series has two wiring schemes, one is for M series
inverter connected to X3-Matebox, and the other is for D series
inverter.
There are different ways of wiring in different countries, one is to
connect N line with PE line, the other is to separate the line from the
PE line wiring, see below;
